Descriptions

An issue was discovered in Mbed TLS 3.5.x before 3.6.0. When negotiating the TLS version on the server side, it can fall back to the TLS 1.2 implementation of the protocol if it is disabled. If the TLS 1.2 implementation was disabled at build time, a TLS 1.2 client could put a TLS 1.3-only server into an infinite loop processing a TLS 1.2 ClientHello, resulting in a denial of service. If the TLS 1.2 implementation was disabled at runtime, a TLS 1.2 client can successfully establish a TLS 1.2 connection with the server.

Se descubrió un problema en Mbed TLS 3.5.x anterior a 3.6.0. Al negociar la versión TLS en el lado del servidor, puede recurrir a la implementación TLS 1.2 del protocolo si está deshabilitada. Si la implementación de TLS 1.2 se deshabilitó en el momento de la compilación, un cliente TLS 1.2 podría colocar un servidor exclusivo de TLS 1.3 en un bucle infinito procesando un ClientHello de TLS 1.2, lo que resultaría en una denegación de servicio. Si la implementación de TLS 1.2 se deshabilitó en tiempo de ejecución, un cliente TLS 1.2 puede establecer exitosamente una conexión TLS 1.2 con el servidor.
